airvpn on Raspberry Pi 4

Recommended Posts

Hi,

I am running the latest version Manjaro ARM minimal on the Raspberry Pi 4. I have no GUI so naturally I generated an .ovpn file to connect with. Both with UDP and TCP I get the following output - with the only difference being whether or not it mentions the use of TCP or UDP:
 

2021-09-14 18:55:38 DEPRECATED OPTION: --cipher set to 'AES-256-CBC' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM). Future OpenVPN version will ignore --cipher for cipher negotiations. Add 'AES-256-CBC' to --data-ciphers or change --cipher 'AES-256-CBC' to --data-ciphers-fallback 'AES-256-CBC' to silence this warning.

I am connected to the internet and have DNS working, as a quick ping reveals:
 
ping -c4 google.com
PING google.com (142.250.200.46) 56(84) bytes of data.

--- google.com ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3005ms
rtt min/avg/max/mdev = 11.504/12.144/13.324/0.700 ms
So I'm not sure what's going on. I am on a subnet with mask 255.255.255.128, but my desktop and laptop and some VM's on the same subnet have no issues using eddie, or .ovpn files for that matter,

As far as I can tell it has something to do with bringing up the interface itself. I have `net-tools` installed, so the use of `ifconfig` should make no difference.

Does anyone have any advice?

That's… rare. Do you get anything back if you execute this?
